In addition to a reference GTX 780 graphics card, Gigabyte is one of the few Nvidia partners that decided to go for a custom cooled and factory-overclocked version as well and launched the Gigabyte GTX 780 Windforce 3X.
Unlike the reference one that uses Nvidia's cooler which we all saw and liked on the GTX Titan, Gigabyte also launched the GV-N780OC-3GD factory-overclocked GTX 780 graphics card with Windforce 3X 450W cooling system. The dual-slot, triple-fan Windforce 3X was enough for Gigabyte to push the GPU clocks up from 863/900MHz to 945/1006MHz. It still comes with 3GB of GDDR5 memory clocked at reference 6008MHz and paired up with a 384-bit memory interface.
The Windforce 3X cooler features three inclined fans and two 8mm and four 6mm heatpipes paired up with a large heatsink which ensures maximum cooling performance at minimum noise levels.
According to what we have seen so far, while reference GTX 780 graphics cards are hitting retail/e-tail at around US $649/€649, custom and factory-overclocked version should be around US $20/€20 or so more expensive.
